Among the twenty-fiDur species above mentioned there will undoubt- 

 edly be a few synonyms, and from the known generic habits there are 

 unquestionably a number of secondary parasites. Brischke has called 

 special attention to the fact that Nos. 17, 21, 22, and 23 are hyper-para- 

 sites, and to these we may unquestionably add 13, and in all probability, 

 14, 15, and 16, as Mesochorus has often been reared from Microgaster co- 

 coons, and as we are not familiar with any cases of primary parasitism 

 in this genus. There is also some little doubt about the species of Cam- 

 poplex, so that only fourteen undoubted primary parasites are left. The 

 majority of these insects are not confined to Ocneria dispar, and some 

 of them are well-known and widely-spread beneficial insects. The Ap- 

 anteles glomeratus, for instance, is a well-known European parasite of 

 the common Cabbage Worm, and occurs quite abundantly in this coun- 

 try. It is almost incredible that the caterpillar should have no Ameri- 

 can parasite, and we imagine that careful study will show that some of 

 our American species of the Microgasterince, at least, will be found to 

 infest it, while predatory insects, of course, are not so strictly confined 

 as to the character of their prey. 



In conclusion we may state that if Professor Fernald's recommenda- 

 tions are carried out at all strictly we have little fear of the spread of 

 this pest, and agree with him that it can be entirely killed out with the 

 expenditure of a little time and money.

THE TRUE CLOTHES-MOTHS * 



"And he, as a rotten thing, consumeth, as a garment, that is moth-eaten." — Job, 

 xiii, 28. 



The true clothes-moths are the housekeepers' dreads, in parts of the 

 country where the Buffalo-bug is not known, and they flourish, though 

 with diminished prominence, through comparison with the Buflfalo-moth, 

 in all sections. They are cosmopolitan insects, having been carried in 

 clothes to all parts of the world, and no one of them is indigenous in 

 the United States, so far as we know. The greatest confusion existed
